Start with the transaction code in the Form 4 row: P means a purchase, S means a sale, and A means a grant, award, or other acquisition from the company. Then check whether the row is in Table I or Table II, confirm whether securities were acquired or disposed, and read the footnotes. An acquisition is not automatically an open-market purchase, and a sale alone does not reveal why the insider sold.
What a Form 4 reports
Form 4 reports changes in beneficial ownership by company insiders, including officers, directors, and holders of more than 10% of a class of securities. It can cover both common stock and derivative securities such as options, warrants, or convertible securities. The SEC says the form generally must be filed within two business days after the transaction date. See the SEC’s Investor Bulletin on Forms 3, 4, and 5.

A Form 4 may contain several transaction rows, and a single filing can include different transaction types. Interpret each row on its own rather than treating the filing as one simple buy or sell.

The transaction code identifies the reported type of transaction. The SEC’s Form 4 instructions and investor bulletin define the common codes below.

| Code | What it generally reports | How to describe it carefully |
|---|---|---|
| P | Purchase | A purchase on an exchange or from another person; check the security, price, and footnotes before calling it an open-market purchase. |
| S | Sale | A sale on an exchange or to another person; check for disclosed plan information and other context. |
| A | Grant, award, or other acquisition from the company | An acquisition from the company, not necessarily a voluntary purchase by the insider. |
| D | Sale or transfer back to the company | A disposition that should not automatically be described as a market sale. |
| F | Payment of an exercise price or tax liability by delivering or withholding securities | May relate to an option exercise or tax withholding rather than a conventional market sale. |
| M | Exercise or conversion of a derivative security | Read the derivative details; this is not by itself a purchase of common stock on the market. |
| G | Gift | A transfer that is not necessarily a market sale or purchase. |
| J | Other transaction | The transaction should be explained in a footnote. |
Distinguish an award from an insider purchase
Code A is the crucial distinction when asking whether an insider bought shares. It identifies a grant, award, or other acquisition from the company. That may increase the insider’s reported holdings, but it is not the same thing as the insider paying to buy shares from the market or another person. Code P is the purchase code.
Do not infer transaction type from the word “acquired,” the number of shares, or an increase in holdings alone. Use the code together with the table, acquired/disposed indicator, and explanatory notes.
Check the table and acquired/disposed indicator
Table I: non-derivative securities
Table I covers non-derivative securities, such as common stock. A P or S row here generally describes a purchase or sale of the listed non-derivative security, subject to the row’s other fields and footnotes.
Table II: derivative securities
Table II covers derivative securities, including options, warrants, and convertible securities. An option grant or exercise is not automatically a common-stock purchase or sale. Check the derivative security description and transaction code before summarizing what happened.
Rank #3
Also look at the column indicating whether securities were acquired or disposed. SEC staff guidance says that this characterization should be consistent with the transaction code; for example, a P-coded purchase should not be marked as a disposition. See the SEC’s beneficial ownership reporting interpretations.
A practical checklist for each transaction row
- Identify who filed and for which issuer. Read the reporting person and issuer names, then note the transaction date.
- Read the transaction code. Treat P as a purchase, S as a sale, and A as a company grant, award, or other acquisition; consult the code definitions for other letters.
- Identify the security and table. Establish whether the row is in Table I or Table II and whether it concerns common stock or a derivative.
- Check acquired versus disposed. Confirm that the indicator is consistent with the transaction code.
- Read the amount, price, and remaining holdings. These fields help show the size and effect of the transaction; note whether ownership is direct or indirect.
- Read every relevant footnote. A note may explain a transaction’s nature or disclose that a sale was made under a Rule 10b5-1 trading plan.
The SEC’s sample Form 4 illustrates the form’s fields and footnotes. In an official example filing, an S-coded sale is explained as having been effected under a Rule 10b5-1 plan adopted earlier; the footnote adds context but does not, by itself, establish the insider’s motive.

No. A reported sale establishes that a transaction was reported; it does not establish the seller’s reason or outlook. The SEC Office of Investor Education and Advocacy notes that insiders may sell for reasons including liquidity and diversification in its February 2013 bulletin, “Insider Transactions and Forms 3, 4, and 5”. A careful description sticks to what the filing discloses, including any reported plan, and avoids assigning a motive without evidence.
